Effects of Immersion Period after Tumbling Processing on the Quality Properties of Boiled Pork Loin with Soy Sauce

Abstract

The purpose of this study was to investigate the effects of immersion period after tumbling on the physicochemical properties of boiled pork loin with soy sauce. After the samples were tumbled for 30 min with soy sauce (1.5% salt concentration), they were immersed for 1, 5 or 10 days. Boiled pork loin was cooked at an internal temperature to . Cooking yields of boiled pork loin were significantly increased with increasing immersion period. The reduction in diameter and thickness for pork loin were significantly decreased with increasing immersion period, but moisture content and water holding capacity were increased. Shear force in the immersed samples after tumbling was significantly lower than in the control. In sensory evaluation color, flavor, texture, and juiciness of boiled pork loin immersed after tumbling should higher ratings than those of control.
